Embodiment
Below, with reference to Fig. 1～Figure 10 execution mode of the present invention is described.In addition, in each figure, identical or suitable member or the identical Reference numeral of element annotation are explained.
Fig. 1 representes the summary of tubular current fuse of the present invention.This fuse is the tubular current fuse, comprising: the cylindrical shell 11 of pottery; Be fixed in the electrode cap 18 at the two ends of this cylindrical shell; And be arranged in the inside through hole 12 of cylindrical shell and open obliquely and be located at electrode cap 18, the fuse between 18 16; It is characterized in that; This tubular current fuse comprises the scolding tin 15 that extends to the orifice ring shape that the inner surface ground of cylindrical shell 11 forms from the end face of cylindrical shell 11, fuse 16 (temporary fixed) is fixed on the end face side of the cylindrical shell of scolding tin 15.
And the end of fuse 16 does not reach the peripheral part of cylindrical shell 11.That is, the end of fuse 16 is fixed on the scolding tin 15 on the end face of being located at cylindrical shell 11, is cut off in the part that is fixed.After fixed cap 18 time, the scolding tin 15 that utilize to cover the edge portion of through hole 12 cover 18 interior scolding tin 19 fusions and the scolding tin 20 that becomes one with being seated in, the end of fuse 16 is connected and fixed on covers 18 inner surface (with reference to Fig. 7, Fig. 9).
Thus, fuse was pulled out to the outer peripheral face of cylindrical shell in the past, and was housed in the groove of being located at outer peripheral face etc. and temporary fixed, and the present invention can apply fuse under the state of tension force, the end of fuse is fixed in scolding tin 15 and is cut off.Thereby, fuse is being applied under the state of tension force, can tilt and not have loosely to open and establish, and need not be located at groove of cylindrical shell outer peripheral face in the past etc., can obtain the tubular current fuse of simplified construction.
Fig. 2～Figure 10 representes the manufacturing approach of the tubular current fuse of one embodiment of the invention.At first, as shown in Figure 2, prepare inner profile with through hole 12 and be the ceramic cylinder 11 of prism-shaped roughly.Then, the tabular scolding tin plate 13 of layout circle on the end face of cylindrical shell 11.Preferred scolding tin plate 13 has hardness in order to form slick and sly curved surface R in cylindrical shell edge portion, and use is 4%～15% scolding tin formation as unleaded Sn-Cu.
Then, as shown in Figure 3, utilize drill jig (punch press) 14 die-cut to through hole 12 on the scolding tin plate 13.Thus; Scolding tin plate 13 distortion, as shown in Figure 4, in the edge portion (bight) of the through hole 12 of the end face of ceramic cylinder 11; Form the scolding tin 15 of orifice ring shape, this scolding tin 15 constitutes by the scolding tin part 15a of ring-type with from the scolding tin part 15b that this scolding tin part 15a extends to the inner peripheral surface of through hole.As above-mentioned, through utilizing drill jig 14 die-cut tabular scolding tin, the opening portion of cylindrical shell 11 is covered by scolding tin 15, extends to the curved surface R of internal face ground formation slyness from the end face of cylindrical shell 11.Embodiment illustrated is only represented an end face of cylindrical shell 11, but forms scolding tin 15 in the both ends of the surface of cylindrical shell 11.
Then, as shown in Figure 5, fuse 16 opened obliquely be located in the through hole 12.Particularly, utilize not shown drill jig to keep cylindrical shell 11, make the through hole 12 of fuse 16 through cylindrical shell 11.Keep the both ends of fuse 16, make the end face of the both ends of fuse 16, apply tension force F to almost parallel and opposite direction with respect to ceramic cylinder.That is, in the not shown end of fuse 16, to applying tension force with the tension force F almost parallel of illustrated end and opposite direction.Fuse 16 keeps tension force F open contact scolding tin 15 under the state of establishing with tension force F.Sliding in state of tension force F is moving to be contacted with scolding tin 15 to fuse 16 bearing, yet scolding tin 15 is the scolding tin of hard, is formed with slick and sly curved surface R in inner peripheral portion, therefore, compares with the bight of in the past ceramic cylinder, can reduce friction and the amount of damage.In addition, for tension force F, be enough with the less tension force that can make 16 of fuses be set as unflagging degree.
In this stage, make the top of heating head 17 contact the fuse 16 on the scolding tin 15a.Contact portion moment on the heating head top of fuse 16 is heated to more than the fusing point of scolding tin.Through this heating, fuse 16 is fused to scolding tin 15a, and in addition, fuse is softening at the head portion of heating head.Because fuse 16 utilizes tension force F to stretch, so in the head portion of heating head, i.e. softening part, fuse is cut off.Fig. 6 representes the state after the cut-out of fuse 16.Under this state, the end 16a of fuse 16 is fixed on the end face of ceramic cylinder 11, tilts and do not have loosely to be opened to be located in the through hole 12 while this fuse 16 is kept tension force F.Embodiment illustrated is only represented an end face of ceramic cylinder 11, yet forms fuse fixed part 16a in the both ends of the surface of ceramic cylinder 11.Scolding tin 15 is projected into through hole 12 inside owing to the pressing force and the heating of heating head 17 are out of shape.The scolding tin of being given prominence to 15 is filled in the through hole 12 when comprising fuse 16.
In addition, in the manufacturing approach of current fuse, cutting off fuse has the whole bag of tricks.At first, the method for utilizing cutter to cut off is arranged.In addition, under the situation of utilizing cutter to cut off, because blade has the life-span, so need periodic replacement.Then, the method that has the tensile load utilized to cut off.But, in this case, for example need the load of 1kg for the fuse maximum gauge, on equipment cost bigger, in addition because breaking load puts on fuse integral body, so when fuse extended, breaking portion might be not necessarily.The method of cutting off through the conquassation fuse is also arranged.But, existing fuse is caused crooked equivalent damage, characteristic reduces such problem.For said method, push the power of fuse and the heat of welding because utilize, cut off through tension force at the softening point of fuse, damage the such problem of fuse so do not produce, can easily cut off with easy device structure.
Then, like Fig. 7 and shown in Figure 8, the lid 18 that inside is comprised scolding tin 19 is embedded in the both ends of ceramic cylinder 11.In Fig. 8, the state that expression fuse end 16a exposes, but shown in Fig. 6 etc., all or part of of fuse end 16a covered by scolding tin 15a.Then, heating covers 18 makes scolding tin 19,15 fusions, fuse end 16a is engaged in covers 18.This STA representation is in Fig. 9.Here, scolding tin 20 forms through scolding tin 19,15 fusions.The manufacturing process that in the chimeric operation of this lid, accomplishes current fuse of the present invention.In addition, carve at this moment, fuse 16 is more or less lax from state shown in Figure 6, but slack is very little.And, because utilizing the scolding tin 19,15 of identical material to be the embedding shape, fuse end 16a is fixed, so can not contain organic matter etc., make operating chacteristics good.In addition, also can shown in figure 10ly in lid 18, form protuberance 18c.Thus, the lid 18 that is entrenched in the end of cylindrical shell 11 is difficult to extract.In addition, in Fig. 7, Figure 10, illustrate the inner scolding tin 19 of lid, yet the amount that needs only the scolding tin of the initial orifice ring shape that forms enough is used to connect fuse 16 and lid 18, just can omit the scolding tin 19 that covers 18 inside.
According to the manufacturing approach of above-mentioned current fuse, through the peritreme portion of running through, utilize drill jig die-cut and form scolding tin in body end surface, regardless of the shape of the edge portion (bight) of bottom ceramic cylinder, all the inner peripheral portion at scolding tin forms slick and sly curved surface R.Thus, the peritreme portion of running through that fuse is contacted becomes slick and sly curved surface R, and can form the scolding tin more soft than pottery, puts on the stress of fuse in the time of can reducing fixing fuse, can reduce the damage of fuse.In addition, more preferably and with the scolding tin that utilizes the orifice ring shape cover the said method of inner peripheral portion and the structure that is pre-formed the fillet (radius of curvature R) of appropriateness in the inner peripheral portion and the outer peripheral edges portion of ceramic cylinder.
In addition; Making fuse pass through through hole and fixedly the time, fuse being stretched along body end surface, fuse is fixed on the scolding tin of body end surface; And, can under the state that fuse is applied tension force, this fuse be tilted and not have loosely to open to be located in the through hole through cutting off fuse.Thus, can reduce deterioration based on the operating chacteristics that causes contact through hole internal face etc. because of fuse is lax.
In addition, when fixing fuse, fuse partly is cut off at the scolding tin of body end surface.Thus, need not fuse is pulled out to the cylindrical shell outer peripheral face, do not need groove 2 necessary in the patent documentation 1, can simplify the structure of cylindrical shell itself, can simplify manufacturing process.Thereby, according to the present invention, be easy to operation, the little tubular current fuse of deviation that can the volume production operating chacteristics through automation.
An execution mode of the present invention more than has been described, but the present invention is not limited to above-mentioned execution mode, in the scope of its technological thought, certainly implements with various mode.
